This wasn't a straight-forward zombie movie. The idea of hybrid
second-generation zombies was pretty interesting (I know other movies have
done zombies-but-they're-getting-smarter, but also, the "Dead" series
definitely got worse as they added that).

I think the movie mostly largely nailed the premise, and used it to some
interesting effect. I also think the acting and interpersonal drama was
good.

I'm not sure the movie completely nailed its justification for the ending.
I get the stance Melanie takes, and I guess I buy that she feels she needs
to take it immediately, but I'm not sure I buy that the movie needed to
have entire-world stakes in it (I guess you could read that it isn't
actually entire-world stakes, or that, alternately, the ending was
incredibly inevitable because that same action could have occurred in any
major city). I also kind of have mixed feelings about this more recent need
to give exact explanations about where zombies come from, but I guess maybe
it's more justifyable here because it makes the symbiosis plot point
easier.

Finally, my fervent plea is that zombie movies just call zombies 'zombies'.
I was fine with this in Rabid
because they didn't give the zombies special names and rabies seemed like a
reasonable guess that early in on that outbreak. The idea that they'd still
be using a bullshit neologism like 'hungries' that far into an infection is
obnoxious.
